Hey guys, hope some of you can help me out. I have a '12 FX4 with the stock 18" wheels. I want to order an Autospring 2" leveling kit and want to keep my stock wheels. I have searched the internet and the forum for the perfect answer but can't seem to find it. What is the largest tires you can fit on these wheels with this leveling kit?

I know the wheel is 7.5in wide, and the biggest tire you can fit on a completely stock truck is 275/70/18. I have seen people use the size 285/75/18 with the leveling kit, but is that really the largest and best looking size? I don't want any rub, just a good, wider looking stance with the tires. Thanks!

 

You should be able to fit a 35/12.5. I did on my 09 with the factory fx4 20's. Had 35/12.50 mudgrapplers.

 

12.5's would be nice. How wide were the '09 wheels? And did the tires throw rocks and debris up the side of the truck and scratch it?
